Why doesn’t your AutoTune use 10/12mm o2 sensors?

Dynojet supplies industry standard Bosch 18mm wideband o2 sensors in our AutoTune kits. 10/12mm wideband o2 sensors are not readily available. To use the AutoTune module, 18mm bungs need to be welded into the headpipes and the 18mm sensors need to be inserted into these bungs. Dynojet has tested a few of the 10/12mm to 18mm adapters and found them to not work correctly.
